Abstract
En 中文
This paper presents the application of the design method introduced in Part I. Design of an axial active magnetic bearing (AMB) is implemented as part of a novel heat pump compressor design. The case study highlights the importance of integrating various design areas to streamline the overall design process. All results are produced exclusively through the design process and methodology outlined in Part I. The study presents geometries for two thrust bearing configurations in relation to the shaft diameter, highlighting the multidisciplinary nature of the design through a sensitivity analysis. Analytical calculation results are compared with finite element simulations, not only to validate the accuracy of the design, but also to generate data that can refine the design details. The key outcome of this study is not the precise design itself, but the clear improvement in the design process efficiency, resulting in a methodology where the bearing design lead time is measured in days rather than weeks or months. Although, not all steps in the design process are entirely accurate and could be further improved, the design method allows easy modification, illustrating the interactions between parameters in this multidisciplinary process.
